myMDnotes

myMDnotes is a privacy-first markdown editor for people who think in diagrams as well as words. Type markdown on the left, watch flowcharts, sequence diagrams, ER diagrams, math equations, and syntax-highlighted code render live on the right — with premium typography that makes your notes feel like a finished document.

Every Mermaid diagram and inline SVG is downloadable as high-quality PNG with one click, and the entire note can be exported to pixel-perfect PDF or HTML. Documents are addressable via short content-hash URLs (`/d/<hash>`), and short notes can even be encoded directly in the URL fragment for instant, server-less sharing.

Everything runs in your browser. No uploads, no tracking, no accounts — your notes are stored locally and only ever leave when you choose to share them.
